For those of you who have converted from the Berkeley db to skiplist, what kind of a
performance improvement did you receive?
We are using Berk. db4 and the IO wait for the disk containing the db is consistantly
over 50%. The partition is 7GB, which also contains the user, quota, proc, and db
directory. It resides on an STK V960 fibre channel, RAID 1 disks. I am seeing
"DBERROR db4: nnnn lockers" errors with the number over 10,000+ ... usually soon
afterwards, the imap process needs to be restarted.
Also, the 'imapd -s' and 'pop3d -s' process unexpectedly dies and SSL connections are
no longer possible until imap process is restarted. Is this a known problem?
Our platform is :
Cyrus 2.1.11
Solaris 8, Sunfire 280R
4GB memory, 2 CPU
Thanks,
Bob
